Battery acid is very caustic! Skin and
eyes can be injured, clothing and
flooring can be damaged.

Rinse skin or body parts that have
come into contact with acid
immediately with running water for
several minutes. Then see a doctor.
Immediately remove clothing wetted
with acid. Wash clothes with soap
solution and rinse with much water.

Always wash your hands after work-
ing on the batteries.
7.5.4 Battery replacement
The daily use of the electric wheelchair
places a high demand on the drive bat-
teries, they can only fulfil their function
when they are maintained and charged.
Batteries undergo a normal ageing proc-
ess. Both batteries must be replaced
when they no longer give the full pow-
er or are defective despite correct charg-
ing.
The use of batteries with different ca-
pacities is not permitted.
☞
Note:
Have a battery replacement carried
out by a specialist workshop because
they know about the possible risk sit-
uations and can correctly dispose of
defective batteries.
7.5.5 Safety information
